iPad Pro gives me:
- amazing SSH terminal
- ability to download content from streaming services to long-haul flights
- a decent size screen for watching TV in bed (my bedroom has a layout that prevents me from placing TV anywhere)
- a good steam/xcloud client
- when latency is too high for SSH, I have RPi I connect with USB-C to iPad and shows up as Ethernet adapter powered from iPad.
- a few games to play on the iPad itself when away
- I have a thunderbolt dock that my main PC is connected to, I can switch to my iPad. That with Stage Manager gives essentially focus-mode mac.
- nice screen (quality and size) to read things (not books, eInk is king there)
- nice screen to look at recipes while I cook
You might notice that none of these tasks require a powerful CPU, and you will be right. I got iPad Pro because of screen size and thunderbolt. Might switch to the new one because the camera is finally in the right place.
If I could run IntelliJ on iPad, even in remote mode - I wouldn't even think about buying a laptop.
